African country during the six months ended January 31, 2004 were 16.0% of total net sales. International sales (including sales to domestic companies for inclusion in products which are sold to international customers) represented 43.5% and 41.0% of total net sales for the six months ended January 31, 2004 and 2003, respectively. Domestic commercial sales represented 14.8% and 17.6% of total net sales for the six months ended January 31, 2004 and 2003, respectively. Sales to the U.S. government (including sales to prime contractors to the U.S. government) represented 41.7% and 41.4% of total net sales for the six months January 31, 2004 and 2003, respectively. Gross Profit.Gross profit was $41.6 million and $25.2 million for the six months ended January 31, 2004 and 2003, respectively, representing an increase of $16.4 million, or 64.9%. The increase was primarily due to the higher sales during the first half of fiscal 2004, as discussed above. Gross margin, as a percentage of net sales, was 36.8% for the six months ended January 31, 2004, as compared to 34.3% for the six months ended January 31, 2003. Although the six months ended January 31, 2004 contained a higher proportion of mobile data communications segment sales, which generally are at lower margins than our other businesses, the impact was offset by sales of high margin earth station products and the greater operating efficiencies associated with the increase in total sales. Included in cost of sales for the six months ended January 31, 2004 and 2003, respectively, are provisions for excess and obsolete inventory of $0.8 million for each respective period. As discussed above under “Critical Accounting Policies - Provisions for Excess and Obsolete Inventory”, we regularly review our inventory and record a provision for excess and obsolete inventory based on historical and future usage assumptions. Selling, General and Administrative Expenses.Selling, general and administrative expenses were $17.4 million and $12.7 million for the six months ended January 31, 2004 and 2003, respectively, representing an increase of $4.7 million, or 36.8%. The increase was due to higher expenses relating to the significant increase in sales and profitability during the fiscal 2004 period as well as compliance costs in connection with recently enacted corporate governance regulations and higher insurance costs. As a percentage of net sales, selling, general and administrative expenses were 15.4% and 17.3% for the six months ended January 31, 2004 and 2003, respectively. Research and Development Expenses.Research and development expenses were $7.2 million and $6.3 million for the six months ended January 31, 2004 and 2003, respectively. Approximately $6.7 million and $5.6 million of such amounts, respectively, related to our telecommunications transmission segment. As an investment for the future, we are continually enhancing our existing products and developing new products and technologies. Whenever possible, we seek customer funding for research and development to adapt our products to specialized customer requirements. During the six months ended January 31, 2004 and 2003, customers reimbursed us $1.3 million and $1.2 million, respectively, which amounts are not reflected in the reported research and development expenses, but are included in sales with the related estimated costs included in cost of sales. Amortization of Intangibles.Amortization of intangibles for the six months ended January 31, 2004 was $1.0 million, as compared to $1.1 million for the six months ended January 31, 2003. The amortization relates to intangibles with definite lives which we acquired in connection with various acquisitions. Operating Income.Operating income for the six months ended January 31, 2004 and 2003, respectively, was $16.0 million and $5.2 million. The increase was the result of the higher sales and gross profit, discussed above, partially offset by higher operating expenses. Operating income in our telecommunications transmission segment increased to $13.8 million for the six months ended January 31, 2004 from $4.6 million for the six months ended January 31, 2003 as a result of significantly higher sales combined with the increased operating efficiencies and overhead absorption. Our mobile data communications segment generated operating income of $5.1 million for the six months ended January 31, 2004 compared to $1.2 million for the six months ended January 31, 2003 due primarily to the increase in sales and more favorable product mix. Operating income in our RF microwave amplifier segment decreased to $0.5 million for the six months ended January 31, 2004 from $1.3 million for the six months ended January 31, 2003 as a result of the decrease in sales. Unallocated expenses increased to $3.4 million for the six months ended January 31, 2004 from $1.9 million for the six months ended January 31, 2003 due primarily to higher incentive compensation expense, increased costs associated with recently enacted corporate governance regulations and higher insurance costs. 15
